- in this video. I make a long light box from 485 white LEDs and then a Super Bright Light from an old LED / LCD Television. ideal for Photography and Filming.
I have to buy most items myself to make these video's so any help would be greatly appreciated "become a Patreon" / markusfuller
You are the first TH-camr that I've seen that actually shows how to trick the LEDs on, thank you
Hi Markus, best recycling tip of the year.
You can correct the blue LED light with a filter in front of the screen. This is better than adjusting the white balance on your camera because you are alteady mixing different types of light.
Try controlling the worst color temperature (your tv-screen-lightbox) at the source with a CTO filter (or experiment with a pale orange transparant piece of plastic). This wil lower the color temperature of the LED.
Thank you for your really interesting video's. I recently used one to fix a small issue with my synth so thumbs up for you.
I have actually built one of these to use as under counter lighting in my kitchen, they work really well and are pretty bright, I used a warmer tone of led strip lights, very fun and cheap to build, thinking of adding more to shelving in my living room and building the boxes out of 1x1 stock with 45" corners, these lights are great, I love your use of an old HDTV.
Great ideas!
BTW, I use the all white photo idea on the monitor for creating a light table for tracing artwork, etc.
thank you so much Markus! was looking for someone who knows how to do the "power signal on trick" for tv-leds quite some time now.. [drum roll] this made my day, prevented purchasing several dcdc-converters and saved me lots of working hours [fanfare] also if there was a ranking for tubers skills "best educational explanations" you'd have me voting 100pt for you [standing ovation]

Brilliant! Really found this quite enlightening. These fixtures will certainly be great filmmaking fixtures. Well done, and thanks for showing this off.
Thankyou Thomas. It took me 3 attempts and 2 days to upload it on youtube. they really are incredibly bright.
I chuckled at 17 minutes when you tossed aside the board and smashed something...unexpected. Good video 👍
I quite liked the way you connected them together. Thanks
Light the LED strip light and what you did with the TV . A close-up of where you soldered the the wire to trick the chip from turning on would have been nice.
thanks for your time and thoughts MarkusFuller
Good work Mark. Well done.
I've been looking at doing this myself, the products in the market are outrageously priced! Thanks for posting.
Thankyou. Its really amazingly bright and the TV was destined for the bin :-(
Great tutorial!! Do you know if the diffuser/lens things in a tv screen /monitor can be cut down to be made smaller?
Thank you for taking the time to make the video.
Is it worth having the cool/ warm white LED's switched so you can have either warm, cool or warn and cool LED's?
+Green Silver yes that would be a great idea.
loved the video:) wanted to ask if it was possible to cut up the tv (led panel) to get a more square shape. Also where can one buy diffusers? I want to make a 40cm square lightbox with an image (on film) mounted to it...would appreciate any advice!
On the TV light box when you installed led the variable resistor, I assume that the grey wire when to the point you found on the LED Driver board you touched using the "human resistor"?
Hi Melanie. it was a long time ago when I made this video but yes I guess you are right in saying it was a human resistor. its a bit dangerous to do but I guess it worked out.
Fantastic idea Marcus!!! I've got to try this myself!! Love the use of warm, and cold white LED's.....!!! Thank you so much for sharing!!
Very nice video ...I liked it... may i know what material is used for diffuse led light??
Hello Santosh. that material was found in the back of an old LCD monitor but I have since replaced it with a piece of normal kitchen greaseproof paper used in cooking which works better.
okay
One question. I have converted one 55" SamsungTV to a similar ligt. Do you know if that Bluish Light got any UV in it ? Also what are those transparent plastic sheets on top of the thick Acrylic sheet in the middle covering those EDGE LEDs
?
Hello there may be some UV light but without a tester one could not really guess. also those different layers of plastic are to make an even distribution of light, they are mainly light guides and have tiny grooves in some of them to direct the light towards the LCD panel.
7:30 What if you took out only the sheets of diffuser plastic, so it's just a light panel and LED panel ¿ Would it give off brighter or dimmer solid colored light ¿
+The Sqoou Hello If you took out the diffuser then you would have some areas of your room with brighter parts than others as each led is not set 100% at the same angle as the next. plus the diffuser does make a softer all round light. but yes in some areas it would seem brighter.
This is a great idea! I've used old computer monitors for my projects in the past.
People pretty much give them away for free :)
+NOVA 9 I find them next to the street bins sometimes.
Great video. Where an I find a shell like the one you used to put the LEDs in??
Wow that backlight! Nothin like good ol eye retina burning blue XD
Hi Markthank you very much for the great ideas I have a question about the long light box , I need to know the power consumption of this light box (because 485 LEDs may consume a lot of power so it may be a disadvantage) and if I want to make one but with less number of LEDs , what is the minimum number to use ?
+Eng. GaMaL Hello Eng. I tried a 12volt 1 amp PSU but it was not enough and the switch mode PSU just made the leds flash. I then tried a 12 volt 3 amp switch mode and that works perfectly.
I have just found another led tv (philips ambilight) and will be making another video soon on that one. Best wishes from Markus.
When you solder the all negative and positive together is that a series circuit?
+anthony “Findenzio” Hom Hello. If you solder all the negatives together and all the positives together that is a parallel circuit, If you solder positive of one to negative of the next then that positive to the next negative in a long chain that is a series circuit.
+markusfuller so is parallel circuit better than series circuit? I'm building a 6" x 12" out of 5 meter led strips you think it would be bright enough ?
Hi Anthony, if you are using the long stick on led strips they are normally 12 volts as they have resistors on them. if its those you will have to make the circuit parallel if you are using a 12volt power supply.
Thanks for making this video. I have read about LED strip lighting and the warm vs cool styles, so it was nice to see how these work and have them explained, thank you.
As for the TV, well, more power to you! I haven't got the guts to mess with something like that! I was cringing when you were about to turn yourself into a resistor! Eek!
But, I see that your hair is not standing on end, and your eyes have not exploded, so it seems to have worked! Whew!
Don't want to lose you and your videos to a cracked flat panel TV!
Hi Clydesight. I think I cooked my braincells many years ago so theres nothing left to damage LOL :-)
markusfuller I watched a video by cassettemaster where he was showing a restored wire recorder he had. He thought he'd done everything correctly, but when he touched the machine to change the wire spool, it gave him a nasty shock! He kept that part in the video to show what can happen with electricity!
I should use more of the spoof reels at the ends of my videos.
I don't wish to sound ignorant, but it never occurred to me that a "black bar" on an LCD TV could be repairable. I never tossed my old TV when I replaced it. I may attempt to fudge my way through fixing it. I have experience working on computers, so confidence is high!
I even know how to solder, but that shouldn't be needed if I just have to press down the connection strip...I hope.
Hi I need serious help in backlighting for inspection panel. Is it possible use AC plug n play with dimmable feature? On what height should I place it to be to have it in 60mm box? And have 1030 lumens for 650 x 350 mm box
Great idea , i wonder if we could do the same with a old laptop screen ?
+Claude Lefebvre Hello Claude, as long as its LED laptop screen There should be no big difference. you can do it with the old CFL tube screens also but I think the LED versions are easier to power and brighter.
Thank you for your answer it is very appreciate !
Thanks for your advice Mark its a great help for non professional people like my self. Kind regards Mark
hey will rubber glove protect u from the shock out those capacitors and in general
Can this be done with a broken desktop monitor and how to keep the screen from turning off automatically??
Nice Vid. I do have a question about an old monitor converted to a light box..... is there a way to get the "screen saver" to stop turning the light off after 2 or 3 min?
Hello I removed the board with the TV-tuner etc and that normally has the screen saving commands on it. I just used the power supply and a resistor to trick it into turning the leds on permanently.
markusfuller Ok. Ill have to go back in and look because I believe the TV board and the control board are one in the same so I may need to find a way to disconnect that part of the board.
Hi Mark will you be doing a program in the near future about how to use an oscilloscope, I have one but don't want to use it as I don't know what voltage I can use it on safely. I find your videos very clear and very informative so please keep it up and thank you. Regards Mark
Hi Lionel. I tend to use a multimeter and if voltages read below a certain level I presume its safe to use the scope. thats only for high voltages that I'm not sure of though. if you set the scope to the highest voltage (normally 20volts per division on the scope screen though some scopes do 50Volts/Div ) then if the waveform fits within the window you can go downwards with the Volts/Div switch until you get a good visible reading. I think Dave at the (youtube) EEVblog has a few good videos on how to use a scope and how not to blow up your scope. I just typed in to youtube "how to use an oscilloscope" and theres lots of videos to choose from already. But in all honesty I don't think I could do a better video on using a scope. my apologies from Markus
Is there a way to do this without an oscilloscope? I have an LED desktop monitor that would be perfect for this
Nice job !!!!! And good Job on the warning folks. ~ Cheers
i have used a Samsung ue46f7080st - it was easy: removed all screws and frames. removed the broken TFT. removed the CPU and GPU circuit boards, keeping only the power circuit board. reassembled the frame. plugged in the power cord. done. lights up insanely bright, consuming 80W. the only problem is, there is a space where the TFT used to be, resulting in the diffusion sheets falling out. u can just hot-glue it under the metal frame
tazztone yes its amazing how bright these tvs are under that lcd panel :-)
do you know what CRI (color rendering index) these LEDs usually have? are they suitable for color accurate illumination?
however i found that they pull much much more power than they need for lighting. so it's much more efficient to measure current and voltage of the strips and buy a dedicated LED driver to power them
Tazztone,
I have successfully added another diffuser panel from another MFR that was the same size. It fills up the space left by the removal of the LCD panel
Where did you get the diffuser material? I am trying to make a similar light box but am having trouble finding a decent diffuser
+Stewart Weinland Hi Stewart, Im not quite sure where it came from, it has been sitting in my workroom for ages but i think it originally came out of a flat screen tv that i disassembled. maybe it was the part under the LCD that diffused the backlighting. though you could use tracing paper it looks the same is easier to cut and I guess it is not too expensive.
hello nice tutorial !!! I wanted to know what is the name of the big black aluminum profile you used or where can I buy it online?
thank you
what type of resistor and how did you wire it please, i could not see the name of the points you soldered
hello i was wondering Can this be made into a grow light? what is the leds output ?
Human resistors are the best! Great power dissipation!
I really enjoyed the explanation clear. Hugs from Brazil
Thanks David.
Great idea. But one thing puzzles me, knowing that the brightness of an LED backlit TV is controlled by PWM, isn't there the possibility of flickering when filmed by a camcorder ? Unless you power them at full brightness all the time ?
Hi Alain. It seems the PWM is split to 4 channels of leds running offset to each other so at least 2 maybe 3 banks are on at once ?. (maybe) it does not seem to flicker through my camera working at 30fps though i have not tested it at 60fps.
markusfuller Thanks for the reply, and the very interesting video ! BTW, what is the total power consumption of those 485 LEDs ?
Hi Alain. the total at 12volts was 0.527A
markusfuller Hello Markus, thanks for that info. Although, I would have expected more than that for high intensity white LEDs, even at 12 V. But with this very reasonable power demand, it could even be powered by batteries for portable use.
AlainHubert aha i think you have a point. I just looked on my notes when i sent you that figure. However i think i wrote that down on testing the roll of warm white leds before i chopped them up and added a whole roll of bright whites into the box. So i guess in total there maybe just over an amp. Im going to test the whole box tomorrow and let you know.
Hi Markus, have u got a suggestion where i can find an aluminum extrusion like yours?
Hello. the long flat housing i used was from a broken message display. I am not sure where you could buy something like this. sorry
Brilliant Markus, thank you! Two really great ideas here!
very interesting as usual, I must have missed this video first time around... but i cant help but wonder a high powered led torch coupled with a suitable enclosure (probably mylar-lined) have been alot easier?
^_^
Great light is always good for Filming . In hindsight I would not recommend keeping the power supply. Instead I recomend to messure the max voltage on the seperate LED lines F.e, with Sony its often 135 V. Than Unsolder the Bridge rectifier, high volatage capacitor and fuseholder from the power supply. Replace the main powersupply cable with a grounded cable. Conect the ground to the chassey. In my case I route the other 3 wires of the 220 V outlet Power to the fuse, than rectify it with the rectifier, flatten the 200V DC with the capacitor and supply two 135V LEDs strings in Line with the 220 DC. Works like a charm. Vou can also add any super small low Voltage DC power supply to drive a DC PWM Dimmer that drives a DC Solid state Relay that drives the LEDs. And there you have it, a dimmable Lamp for a couple of bugs.
Awesome! great!!! thanks! The only problem Iam having is how to make it stand on its own like with a light stand, still unable to do it, I dont want it to be sitting in a table or on the floor.
+Roberto Steve Lou Hi Roberto. I placed my flat TV light on a computer monitor stand so I can attach it to a desk and move it around, but as for use on a light stand I can only say experiment as im sure you can make something up. there are stands for TVs & monitors available but they are quite expensive.
thanks a lot
what kind of light filter would you need to create more of a white light?
+NOVA 9 Hmm thats a good question that I dont really have the answer to. if its too blue i would try a slight pink/red cover for part of it just to warm the light a little. but I do not know enough about filters to answer that . sorry.
I have Westinghouse 32in stripped to the bones, i was wondering if i could put a current through the light bars without using any of the circuit board. Also what would be the wattage of the light bars.
Chase Scott when you say light bars do you mean like thin flourescent tubes ?. as you would need to keep some of the circuit board to light the flourescent tubes. if they are led then you would still require a pretty beefy power supply to light those also.
Cool idea, this is going to seriously affect light spectrum though eh?
I scrap flat screen TVs amongst all kind of things, for metal scrapping. I have been carefully removing and saving the LED lite strips from the TVs, because I had this notion that I could make some of my own funky lights with them. However, my knowledge is quite limited when it comes to understanding voltage and amperage, direct current, and all that important to know, electrical know how. I am hoping that your video will be one among many, that helps me figure out how to properly wire up, and power up these LED strips. Maybe you could do a "basics" video, to show us how? What are the proper steps to correctly power a single LED strip for plugging into a wall outlet. I am in the U.S., so maybe some principals will be slightly different from your overall electric set-up in your Country? I don't think simply joining a plugin cord to the two leads, is the right procedure.
'
wow that cooooool nice LED light on the TV monitor for electronics / hobbys
u r a genius man. awesome work
Did you wire the LED in parallel or series ? Great video, Keep up the good work. Enjoyed watching it.
Gilbert Boshell Hello the strips are wired in parallel
Thanks for answering my question, I appreciate it very much.
I wanted to figure out how to do something like this to make a light box for tracing, so thanks.
Very interesting! Thank you!
Great video, Noticed your ham radios in the back ground 73's from N5SLI
Patrick Patterson 73 (best regards) thanks Patrick. :-) I wish I had completed my ham licence years ago but got distracted with too much work and no free time so was always putting it off for another day. still I may try again one day . many thanks.
Getting your license, is easy as pie. No morse code required, just a multiple choice test. You can practice for the test for free at www.qrz.com/hamtest/
Patrick Patterson Thanks Patrick I shall go and look into that.
Weldone , nice video, gave me ideas to try, thank you.
What the name off aluminium?? Where u buy?? Can someone answer me?
Is there a way to avoid soldering? I would rather not have to do that part
Hello Oscargt23 if you want to make the lightbox with the long strips of leds then you can buy edge connectors that you can just clip onto the edges of the strips. they are made with leads on them and also corner pieces and end to end connectors. just look for led strip end connectors on the internet.
Awesome video!
It shouldn't be that much of a problem that the lights are a bit cold, you can adjust the white balance in your camera (and in post-production) so that the blue-tinted white of the light is considered pure white by the camera.
If you really want to make it simply for you, get a gray paper/card (50% gray is the best) and hold it up infront of the camera where you're sitting, with the lights on, film a second or two. Then in the computer, you can create a white balance profile with the editing software, by selecting the gray paper/card as the white balance spot. And then just load that profile for any video you shoot with these lights.
I hope that makes sense for you.
Hi Erik. Yes makes sense indeed. Thankyou
Hi
I like your videos i´m suscribed
I want to ask you How can i use this kind of led for ilumination at home like a bulb?
I want to have 30w for my living my room etc..
I live in colombia and here we have 120V AC
Can you suggest me a page or a tutorial were i find the info i need?
Thanks
Hello you would be better to buy a flat panel led light from amazon or some other electrical retailer. I have one in my workroom and it is 20cm X 80cm and cost about £30uk pounds but it is made correctly as ceiling lighting and with the correct voltage adaptor for the country you order it for. much easier that hacking a TV and will last many years.
may I know the reason for two different types of light? line warm white and cold white? why can't we use the single type? is there any reason?
Chetan Kale Hello the difference is only the colour temperature of the light, you can have a warmer feel softer light or a colder clinical type of light, the preference is up to what you prefer. my cold light has a lot of blue in it and the warm light a slight red/orange. I prefer warm white.
markusfuller thanks for such a super quick response.
Ahahahaa!! Was that a genuine smash at 17:04?? :D Brilliant.
You should definitely make that a soundbite in future videos when you throw waste to the side xD
+Hewy Greyhat Hi no it was just a soundbite :-)
here is the question though,
how much WATTS does it use of electricity per month while constantly using this.? :)
hey friend
I have Lg smart tv and its broken, so I did what you do in the vedio and its work fine but after about 5 minute the screen turn off and it need to turn on again by remot control, how can I fix this ?
Hi It may be that the TV is waiting for a video signal or tv signal and if it is not receiving anything it is going into power save mode. I do not think you will find a way around this unless you know the combination of buttons used on the remote to access the menu and turn off power saving mode. of course with no screen it will be very difficult.
great man... really great work
I really think you should do the math on how much power you really need including at least 25 percent extra. Just by the looks of it I would have at least an 8 amp power supply adapter.
barry brenner I am using a 5amp power supply and its completely fine. I still use it often when i’m filming.
ZickZack...03:15 brilliant idea!! Thanks for that!!! I have build some LED-stripe-lights too and can use your method for my last panel ;-))
+Studio Bonn Thanks ZickZack. Im working on a new one at the moment where you can change colours but am waiting for a few components so it may be a while before the project is complete and filmed. Best wishes from Markus.
6:03 🤣Nice one! Big fan of the corny jokes....
where did you got the strip led?
+anthony “Findenzio” Hom Hello you can search for led strip on ebay , amazon , or just on the net. they are reasonably cheap but its better to look at how many leds per meter you are getting before you buy and also of they are 5050 leds which are bigger. some strips have 30 leds per meter and some 60 or more but the cost creeps up. all you need is a 12 volt power supply which in some ebay listings they are supplied with the roll of leds. Best wishes from markus
+markusfuller hey thanks do you know how dim them?
Hi Anthony. you can use Pulse wave modulation but that creates flicker on camera or you can use a variable power supply and lower the voltage going into them. I prefer the variable power supply as that does not create any flicker or strobing effect for the camera
oh thanks. is 12 volt power supply good?
Yes 12 volts is normally what these LED strips need but you may need a chunky power supply with a couple of amps output to get good brightness of you are using long lengths of these LED strips. Many companies sell the PSU with the LED strips.
hey. I wanna make something like this with led laptop screen. but I have a problem that I dont know how to power up the backlight. I tested several voltage but it still wont turn on. I need a reply pls
Hello It can be difficult to find the correct voltages used in a laptop screen as it could be anywhere between 12 and 48 volts plus the leds maybe working in a matrix ie half on half off depending on if the control voltage is dc or ac. it really is better to keep the laptop psu as it will have some of the voltage controls for the screen within it. its much easier with a television set.
+markusfuller meh nwm.i tried to hooo it up with the laptop psu itself, but it lighted up dimly. After playing with the screen for a while, I hooked up 2 12v battery (24v) and it happened to turn on. Btw thank you
+markusfuller meh nwm.i tried to hooo it up with the laptop psu itself, but it lighted up dimly. After playing with the screen for a while, I hooked up 2 12v battery (24v) and it happened to turn on. Btw thank you
How's the brightness of a light made from TV compared to the led strip one? It's hard to tell from the video
Hi Pawel. the screen is brighter than the led strip. it uses higher brightness leds but at Pulse Width Modulation. The longer light box is running at standard 12volts DC. I could make it brighter but I may kill the Leds in doing so. but together they are quite blinding so I am facing the up to the ceiling to bounce the light around as it hurts to have it directly facing your eyes for too long.
markusfuller Great! Since it has much bigger surface than LED strip, it makes a perfect and super cheap (if you buy used or broken ones) light source for photography and videography (of course after some color adjustments). Thanks for the tip, being a photographer I'll definitely look into it.
Paweł Rychert I see lots of them at the recycling centre but Im not sure if they will actually sell them to me. there are so many health & safety rules and regulations now and the problem that everyone wants to sue each other for the slightest thing that I'm sure they will too frightened to sell anything to anybody and would rather just bury everything under the land or burn it even though they call it a recycling centre. ( ps Im talking about the UK )
TIP: Put two switches on the first light box, one to switch on the cold white and one for switching on the warm leds, that way you can select the Color temperature (cold, warm or both).
I agree, I keep on thinking about making some changes to it but never get the time. I though maybe a PWM dimmer for both cold and warm could be useful but its a project for another day.
men good job the two acrylics you don't even notice that theres is two parts of them
Good on you mate, I came to see your video to find out how or why won't my LCD TV light up, because its LED light panel won't fire up, but sound comes, and when i shine a bright light from the front you can see the picture, and get access to various Menu, and so i checked to make sure that Brightness and contrast were turned fully on, by shining a torch light you can see these quite effectively, and set the controls but still it did not light up, looks like my Power supply is Ok as i was getting 25v and my tv has only two wires to its LED panel, so i am presuming that if it has several white LEDs and each drops a 3v forward voltage drop of a white LED, so if you have strings of 20 LEDs that means my powersupply should feed 60 odd volts, but this is where the problem is, so my control chip either does not function any more or another chip further down on the TV board does not send control signals.So i am pretty much stuck not knowing which of the two boards is the problem.
Mine is a Toshiba 32" LCD TV. bugger! ,
+Jayant Desai Have a look on the board for a tiny surface mount fuse (F1) near the connector that leads off to the LED strip. I repaired a Toshiba a while back with the same problem though it fed 48 volts to the LEDS. good luck I hope you find the problem.
Thanks Mark, it turned out to be one LED blown off among 24 LEDs ( 12 in each row,) I managed to replace just the one that was blown, and in the end guess what? the flippin screen cracked as i was fitting it back, and I have no idea how the heck did that happen despite taking great caution! it has now been binned! sadly .
Hi Jayant Sorry to hear the screen got cracked, it is so easily done, thats why I do not repair things for other people as there is is always the chance I can make the problem worse. Oh well better luck next time.
How do I stop a backlight from auto dimming without being able to see the menu on the screen?
the auto dimming feature is controller from the main TV board. I bypassed that part altogether and just ran it direct from the Power board but you have to trick it with a resistor so it thinks the main board is requesting the screen to be lit so it lights up. theres so many types of this board you will have to dig in and figure out how to trick it. be careful though there are some very high voltages within that power board. good luck.
Brilliant!
This video has really inspired me to make something similar. Also, is it me or did anybody else think this guy was colinfurze at first??
+DJ JAKEY Hi DJ Jakey, I get that comment quite often about Colin Furze. I think im old enough to be his dad but I love his videos and am subscribed.
markusfuller yeah his videos are great. Yours are really inspiring me to make stuff too..
Thank you.
All I had to do to get the backlight to turn on was cut the ribbon going to the pixel board, and remove it. The tv still thinks it's sending picture, so turns on the backlight.
Francisco, I cut out the ribbon cable going to the AV board, or is it the T-con board? Whether you cut it or disconnect it, the light still goes off automatically after about 15 minutes.
"I was never very bright at school". Lol!
Dave M light humor?
why not just remove the lcd screen from the tv and call it good? not very tech savy but it seems this might be much easier
Most TVs have an atuo-off feature if they don't get a signal of some sort. So it may work but only for 5-15 minutes at a time depending on how that TV is programmed (sometimes it's a setting in the TV but if the TV is no longer useful as a TV, you wont likely be able to navigate the menus to turn it off).
lol glass breaking sound at 17:00
xD
Giuseppe Testa fake sound
liked it good info and nice vid thnxs for that.
cool. someone has found a new purpose for all these expensive TVs which would otherwise be scrapped. one little tap to the screen and they're ruined.
You made this just so you could have a pink jumper, right? :-P
Hi Rennie Ash, I never really noticed that until you mentioned it. yes it does go a bit pink doesn't it. :-)
markusfuller I prefer the led bar due to less blue colour. I also have a screen, but it had the turn on/off randomly issue, so I'm not sure if the power supply is bad or not. Can I power the led with just DC voltage or does it need all the circuits?
17:03 omg lol
Nice..
Amazing
exelente men gracias
It kind of limits what you can do with these, when they go off every 15 minutes. Does ANYONE know how to get around the turn off. Is it due to not having an input signal on an HDMI port, or a protection issue with the power board.
Someone must know what causes this and how to get around it, irrespective of manufacture.
doesn't your lights require very little energy?
+Benny ofAtlanta Compared to old fashioned filament lamps these use about 15 to 20% of the energy as they are just LED lamps.
Thankyou very much :-)
Any idea what the wattage is on them
Oli Reid to be honest I havn’t a clue
I read that these lights cast UV radiation. I burned my eyes on a 49 inch LED playing games. I took that TV back lol I was bummed
i tried. and it keeps turning off automatically
Hello Jacob, it may be that the power supply is not strong enough to light all the leds. you may need to find one that has a greater amp rating but still only 12 volts. my first power supply i tried just made the leds flash as the PSU kept switching off.
i still have the "motherboard" attached to it because i dont got almost any tolls but i kind of fixed it when attached usb in it... usually the lights stayed on about 15minutes and now about 5-6hours... iwas thinking maybe it was the tv's power saving mode that turned it off or something like that
oh good point maybe there is a power save. I thought you were just lighting the leds directly from a psu. the motherboard may have interfered with the timeout.
